If you've ever wondered whether your business needs a policy, a procedure or a Standard Operating Procedure (SOP), you're not alone. These terms are often used interchangeably, but they serve different purposes within an organisation.
Understanding the differences is essential for improving consistency, meeting compliance requirements and creating an organised business. Read our complete guide on Standard Operating Procedures for UK Businesses to understand the full scope of SOP development and implementation.
What Is a Policy?
A policy is a high-level statement that explains your organisation's rules, intentions or principles.
Policies answer the question: "What is our organisation's position?"
Policies provide direction but usually don't explain exactly how work should be completed.
Examples include Health & Safety Policy, Data Protection Policy, Equal Opportunities Policy, Environmental Policy and Anti-Bribery Policy.
Policies are usually approved by senior management and apply across the organisation. Read our guide on how SOPs improve business governance to understand how policies, procedures and SOPs work together within a governance framework. Our Policy Management SOP Template provides a structured framework for creating, reviewing and approving company policies.
What Is a Procedure?
A procedure explains the sequence of steps required to complete a business process.
Procedures answer: "How should this process be completed?"
Examples include employee onboarding procedure, customer complaint procedure, purchasing procedure, recruitment procedure and document control procedure.
Procedures provide more detail than policies but remain relatively broad. Read our complete guide on Document Control Procedures for ISO 9001 compliance to understand how document management procedures connect to your wider quality management system.
What Is a Standard Operating Procedure (SOP)?
A Standard Operating Procedure provides detailed, step-by-step instructions for carrying out a specific task consistently.
An SOP answers: "Exactly how should this task be performed?"
Unlike procedures, SOPs often include responsibilities, required equipment, safety requirements, quality checks, records and version control information.
Read our guide on How to Write a Standard Operating Procedure for a detailed step-by-step walkthrough of creating effective SOPs.
Key Differences at a Glance
A Policy sets the organisational position and intent. A Procedure explains the sequence of steps for a process. An SOP provides detailed task-level instructions with responsibilities, checks and records.
Together, these three document types create a complete operational documentation framework.
Why Businesses Need All Three
Policies, procedures and SOPs work together to create a consistent, compliant and well-governed organisation.
- Policies set the direction
- Procedures define the process
- SOPs explain exactly how each task is completed
Without all three, organisations often experience inconsistency, compliance gaps and poor accountability. Read our complete guide on ISO 9001 Standard Operating Procedures to understand how these documents connect to quality management certification requirements.

Common Mistakes
Many organisations make the mistake of using these terms interchangeably, creating documents that are too vague to be useful, failing to link policies to supporting procedures and SOPs, or not reviewing documents regularly.
A structured document control system helps prevent these problems. Our Document Control SOP Template ensures all policies, procedures and SOPs are version-controlled, approved and retained correctly.
Frequently Asked Questions
Can a policy and procedure be combined?
Yes. Many organisations combine policies and procedures into a single document, particularly for smaller processes. However, keeping them separate improves clarity as the organisation grows.
Do all businesses need SOPs?
Yes. Any organisation that wants to operate consistently, train staff effectively and demonstrate compliance will benefit from documented SOPs. Read our guide on why every growing business needs SOPs to understand the business case.
How often should these documents be reviewed?
At least annually, or whenever processes, regulations or organisational structures change. Read our complete guide on Internal Audit Procedures to understand how regular audits support document review cycles.
